Management/clarification of parenthetical margins:
372438005 |Presence of neoplasm at deep (radial) surgical margin of excised specimen (observable entity)|
384786009 |Status of surgical lateral (mucosal/mural) margin involvement by tumor (observable entity)| Not completed
Scott Campbell to engage CAP to find historical references to disambiguate these terms and address parenthetical terms
Scott Campbell discussed with Richard Moldwin at CAP. Parenthetical margins represent historical artifacts that no longer pertain. These pertain to colorectal cancers and can be modeled appropriately with removed of parenthetical references.
Modeling of "Presence" and "Extent of presence" of X at margin Y
Are distinct concepts needed or can this be managed by synonyms
These concepts will remain as ordinal. Presence of the neoplasm at the margin is the primary use case. However, degrees of presence are possible in some organ systems. Pathology language as used in value sets is ambiguous. The group decision is to use "extent of presence" in synonyms but not in the FSN for concepts. FSN's will only state "Presence"
